CORE-HEATING SAD-IRON.

SPECIFICATION forming part of Letters Patent No. 616,896, dated January 3, 1899.

Application filed May 31, 1898. Serial No. 682,166. (No model.)

r0 all whom it may concern.-

Be it known that I, HORACE P. CARVER, a citizen of the United States, residing at Racine, in the county of Racine and State of Wisconsin, have invented certain new and useful Improvements in Core-Heating Sad- Irons; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention is an improvement in coreheating sad-irons and it consists in the novel features of construction and combination of parts hereinafter fully described, reference being had to the accompanying drawings, which illustrate the best form in which I have contemplated embodying my invention, and said invention is fully disclosed in the following description and claims.

Referring to the drawings, Figure 1 represents a perspective view of my improved sadiron and the fiuting p1ate adapted for use therewith. Fig. 2 represents a vertical longitudinal sectional view of the same, a portion of the handle being shown in elevation. Fig. 3 represents details of the mechanism for locking the iron in different positions with respect to the handle. Fig. 4 is a perspective view of the core. Fig. 5 is a sectional view of the handle structure. Fig. 6 is an end view of one of the trunnions of the hollow body, showing a modification of the lockingrecess shown in Fig. 3.

In the drawings, A represents the hollow body of the iron, which has two fiat faces a parallel with each other and which I term smoothing-faces and two curved faces a of opposite curvature meeting each other and forming sharp end portions. The hollow body A is provided with an aperture on one of its curved sides, which is closed by a curved door o of substantially the full width of the interior of the said hollow body and is hinged thereto at one end, as shown at a One end of the hollow body is provided with a cylindrical trunnion a which is engaged by a similarly-shaped bearing-recess?) on the lower end of one of the handle-arms B, (see Fig. 2,) forming a pivotal connection between the handle and the hollow body. The other end of the said hollow body is also provided with a cylindrical trunnion 0 adapted to be engaged by a similar bearing-recess b at the lower end of the handle-arm B. (See Figs. 2 and 3.) The trunnion a has a longitudinally-extending recess on the side adjacent to the door a to receive a locking arm, stud, or projection a, secured to the door,and which lies in the said recess when the door is closed, as shown in Figs. 2 and 3. The wall of the bearing-recess b of handle-arm B is cut away at one point 5 to form a notch of suflicient width to permit the passage of the arm or stud a, and this notch b is located at such a point that it will be in line with the stud a only when the handle is out of either of its operative positions. When the door is closed and the handle is moved into any one of its operative positions with respect to the body of the iron, the stud a will be confined within the recess 1) of the handle-arm B, as will be readily understood, and the door will be locked in its closed position. The arm or stud a is provided with a projection of, which can be engaged by a suitable tool, such as a stovelid lifter of any usual or preferred construction, for the purpose of opening the door to remove or insert the metallic core.

I provide a very effective and desirable means for locking the handle and the body of the iron in the various operative positions to which they may be moved for the purpose of utilizing one or the other of its smoothingfaces a or the fluting-ribs a which are provided on the curved face of the iron opposite the door, as shown. The handle-arm B is provided with a'pivoted locking-lever O, which is preferably pivoted in ears 12 secured to said handle-arm, and is provided at its upper end with a finger-piece c and at its other end with a square or polygonal plug 0. This locking-plug c is of sufficient length to pass through a. similarly-shaped aperture 19 in the arm B in line with the trunnion a and to enter a suitably-shaped recess a in said trunnion. (See Fig. 3.) In this instance I have shown a square locking-plug passing through a square hole b and engaging a square recess a", and this is my preferred construction, ex-

cept that I may in some cases provide the trunnion o with a transverse notch or recess of the same width as the plug 0 instead of a square aperture, as shown in Fig. 6.

The upper ends of the handle-arms B B are bent inwardly toward each other, as shown, and are provided with circular portions 5 each of which has a central opening I) and an eccentric stud W.

B represents the handle proper, which I prefer to make of wood or other non-heat-conducting material and which is provided with a straight longitudinal aperture b for the passage of a securing-bolt 71 although the handle is preferably given a suitable curvature to adapt itself to the grasp of the hand. At each end the handle 13 is provided with an eccentric recess Z9 which is engaged by one of the studs b on the handle-arm to prevent the handle from turning upon the fas tening-bolt. The fastening-bolt is preferably provided at one end with a screw-head and at the other end with screw-threads to engage the threaded interior of the central opening of one of the handle-arm portions, so that by screwing up the said bolt the handlearms and handle are fastened securely together. By this construction the handle can be cheaply made and quickly and easily assembled.

In Fig. 4: I have shown the core D which I prefer to employ with my improved iron. This core is provided with a central recess d, extending therethrough parallel to the flat faces (2 of the core, which conforms to the shape of the interior of the hollow body of the iron. This recess cl is for the purpose of allowing the core to be more quickly raised to a high temperature than could be done if it were solid by allowing the products of combustion to pass through it. The recess for a small portion of its length is made of considerable width, as shown at d Figs. 2 and 4, while for the greater portion of its length it is extremely narrow. It will thus be seen that the products of combustion can freely enter the core and will have a large amount of surface to engage within the core, while the weight of the core is not very materially reduced, thus allowing the core to contain sufficient metal to retain its heat for a considerable period. It will also be noted that the smooth faces d, which engage the inner sides of the smooth faces a of the iron, are not perforated, so that they will engage the faces a of the iron substantially at all points and will thoroughly heat and maintain the temperature of the said faces, by which the most of the ironing is done.

By reference to Figs. 2 and l it will also be seen that while the recess d presents a continuous opening on one side of the core, the one which is nearest the door in use, the opposite face presents two isolated apertures communicating with said recess, as shown, leaving a solid portion d between them, and as both apertures are of comparatively small extent this face of the core,which is intended to heat the tinting-face of the iron when it is in use, will present almost its complete surface to the inner side of said tinting-face, thus insuring that the flirting-face shall be quickly raised to and properly maintained at a high temperature. The construction of this core is an important feature of my invention, as a core of such construction can be very rapidly heated over coals, a gas-stove, or any other form of heating apparatus and yet will furnish the largest possible amount of heat radiating and transmitting surface when in use within the hollow shell or body of the iron.

E represents a fluting-plate designed for use in connection with the curved fiutingface a of the iron. This plate is supported upon four or more feet 6 and is provided at one end with an aperture 6' to receive a lifting-tool by which it may be handled when hot. The flirting-face a may also be used as a polishing-surface in the use of paraffin or other polishing material in laundry-work.

What I claim, and desire to secure by Letters Patent, is-- 1. In a sad-iron the combination with the hollow main body provided with parallel smoothing-faces, and oppositely-curved faces disposed perpendicularly to the smoothingfaces, one of which is provided with flutingribs, of a core adapted to fit the interior of said body, having non-perforated flat faces for engaging the inner sides of said smoothing-faces, and oppositely-curved faces perpendicular to said flat faces, said core having a central heating-recess extending through the same parallel to the fiat faces and communicating with narrow openings in one of the curved faces, whereby a great amount of surface of said core will be in contact with the smoothing-faces and tinting-face of the body when the iron is in use, substantially as described.

2. In a sad-iron, the combination with the hollow main body provided at each end with a cylindrical trunnion, one of said trunnions being provided with a longitudinal recess, of a door pivoted to said main body at one end and provided with a stud to engage the re cess in said trunnion, said stud having its exterior conforming to the exterior of the trunnion, a pair of handle-arms, provided at their lower ends with bearing-recesses to fit over said trunnions, one of said arms having its bearing portion provided with a cut-away part, to permit the passage of the door-stud therethrough, a handle interposed between the upper ends of said handle-arms and securing devices for uniting the handle and said arms, and forming the sole means for holding the handle-arms in engagement with said trunnions, substantially as described.

3. In a sad-iron, the combination with the hollow body provided at each end with a cylindrical trunnion, one of which has a longitudinal recess, and a door hinged to said main body and a stud adapted to be in and fill said recess, of the handle-arms provided at their lower ends with bearing-recesses to fit over said trunnions, one of said recessed portions having a cut-away part to permit ICC the passage of the door-stud therethrough, a handle interposed between the upper ends of said handle-arms, a connecting-bolt uniting said handle and handle-arms and forming the sole means for holding said handle-arms in engagement with said trunnions, a pivoted locking-lever in one. of said arms provided at one end with a square locking-plug extending through the 1 adjacent recessed portion and engaging a square aperture in the trunnion, substantially as described.

4. In a sad-iron, the combination with the hollow main body provided at each end with a trunnion, of a handle comprisinga pair of handle-arms each provided with a bearingrecess at its lower end adapted to fit over one of said trunnions, a hand portion interposed between the upper ends of said arms, and a securing-bolt passing through said arms and hand portion and holding said arms in engagement with said trunnions, one of said trunnions being provided with a polygonal aperture, and the arm engaging the same having a polygonal aperture,registerin g with said aperture, a locking-lever pivotally mounted on said arm and provided with a polygonal locking-plug, for engaging said aperture in the arm and trunnion, substantially as described.

In testimony whereof I affix my signature in the presence of two witnesses.
